集中空调冷水机组配置及水系统能耗分析
Selection of water chiller units and energy consumption of water system
摘要：
结合某综合购物中心，介绍了集中空调冷水机组的配置原则和方法。比较了三种常用空调水系统的特点及适用场合。采用传递函数法计算了该建筑物的全年动态冷负荷，并利用能耗分析软件，计算出三种水系统的年运行费用。通过对初投资和年运行费用的比较、分析，选出最优的水系统方案。

Abstract：
With a comprehensive shopping center, presents the principle and method of central water chiller unit selection. Compares the characteristics and application occasions of three common water systems. Calculates the annual dynamic cooling loads by transfer function method, and calculates the operation expense of three common water systems by energy consumption analysis software. Based on comparison and analyses of the initial investment and annual operation cost, obtains the optimal water system scheme.
